Key features

The DIN 15237 elevator bucket bolt uses a wide round head to provide a larger bearing area, making it suitable for securing buckets to conveyor belts and elevator systems.

Four pointed projections beneath the head give the four-prong bucket bolt an anti-rotation function by gripping the mounting surface during tightening.

Supplied with a large domed washer and hex nut, the complete elevator bolt assembly helps spread fastening pressure over a wider area and improves connection stability.

Available in M7-M12 metric sizes, this carbon steel conveyor bucket fastener can be supplied in different bolt lengths and Grade 4.6 or 8.8 options according to working load requirements.

Head diameter, prong geometry, washer dimensions, thread length, material, surface treatment, and packaging can be customized for bulk material handling fasteners and conveyor equipment projects.

Product Q&A

Q:Where are elevator bucket bolts commonly used?

The bucket elevator fastener is mainly used for attaching elevator buckets to rubber or reinforced conveyor belts in grain handling, cement plants, mining, feed processing, and other bulk conveying equipment.

Q:Why does this bolt have prongs under the head?

The prongs on a fanged belt bolt bite into the belt or mounting surface to reduce bolt rotation while the nut is tightened, making assembly more efficient and secure.

Q:How do I choose the correct bolt length?

The required elevator bucket bolt length depends on the combined thickness of the bucket, belt, washer, and required nut engagement. Drawings or installation dimensions are recommended for accurate selection.

Q:Can different washer shapes be supplied?

Yes. The conveyor belt bolt set can be matched with domed, oval, or other large-area washers according to the belt structure, bucket design, and load distribution requirement.

Q:What finishes are available for carbon steel bucket bolts?

Common options for industrial bucket bolts include Black Oxide, Zinc Plated, Hot Dip Galvanized, Dacromet, and Plain/Oil, selected according to corrosion resistance and operating environment.
